Are WASP-107-like Systems Consistent with High-eccentricity Migration?

The Astrophysical Journal
WASP-107 b seems to be a poster child of the long-suspected high-eccentricity migration scenario. It is on a 5.7 day, polar orbit. The planet is Jupiter-like in radius but Neptune-like in mass with exceptionally low density.

No Strong Associations between Eccentricity and Orbital Architecture in Kepler Compact Multis

The Astronomical Journal
The dynamical history of a planetary system is recorded in the present day architecture of its constituent planets’ sizes, orbital periods, and eccentricities.

Planet Mass Function around M Stars at 1–10 au: A Plethora of Sub-Earth Mass Objects

The Astrophysical Journal
Small planets (≲1 M _⊕ ) at intermediate orbital distances (∼1 au) represent an uncharted territory in exoplanetary science. The upcoming microlensing survey by the Nancy Grace Roman Space Telescope will be sensitive to objects as light as Ganymede and ...

Boundary Layers of Circumplanetary Disks around Spinning Planets. II. Global Modes with Azimuthal Magnetic Fields

The Astrophysical Journal
The accretion of material from disks onto weakly magnetized objects invariably involves its traversal through a material surface, known as the boundary layer (BL).

Constraints on the Orbit of the Young Substellar Companion GQ Lup B from High-resolution Spectroscopy and VLTI/GRAVITY Astrometry

The Astrophysical Journal
Understanding the orbits of giant planets is critical for testing planet formation models, particularly at wide separations (>10 au) where traditional core accretion becomes inefficient.

Magma Ocean Interactions Can Explain JWST Observations of the Sub-Neptune TOI-270 d

The Astrophysical Journal
Sub-Neptunes with substantial atmospheres may possess magma oceans in contact with the overlying gas, with chemical interactions between the atmosphere and magma playing an important role in shaping atmospheric composition.
